When endpoints fail the policy assessment, the Cisco ISE must create a record with sufficient detail suitable for forwarding to a remediation server for automated remediation or sending to the user for manual remediation. This is required for compliance with C2C Step 3.

Description
Failing the NAC assessment means that an unauthorized machine has attempted to access the secure network. Without generating log records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one.
